Grass and the Environment

Supplier News

Green Life Turf is a quality grower and supplier of turf grass varieties in Sydney. This article discusses the positive impact of grass lawns on the environment.

Global warming refers to the warming of the atmosphere that takes place as a result of human actions.

Lawns have a cooling effect on the environment. Compared to bare ground, grass will reduce the surrounding surface temperature by 15°C.

A neighbourhood of eight average-sized lawns for instance, would have a cooling effect equivalent to 70 tonnes of air conditioning.

The lawn also functions as an efficient filter. Grass absorbs CO2, various hydrocarbons and a range of poisonous gases, converting them to oxygen.

In fact 25 metres of lawn will produce sufficient oxygen to generate a quality of air suitable for a family of four.

It is also estimated that grass traps 12 million tons of dust annually (on a global scale), filtering the pollutants as the dust is washed back to the soil during periods of rainfall.

Perhaps the most significant benefit that lawns can have for the environment is their capacity to cleanse the water supply.

Rainfall washes and carries pollutants from the atmosphere through the root systems of the lawn. A 100 square metres of lawn can develop a maze of 500 million km of roots, which trap pollutants before they pollute the ground water supply.

With the help of soil microbes, the grass converts most of these pollutants into harmless organic compounds that build up the soil to support more life.
